A 12 meter long blob was found on a beach in Chile. It was suspected of being a giant octopus. Turned out to be decayed whale blubber.
2003-04-01 (UPDATED 2003-05-24) Colossal Squid Caught
Fishermen near Antarctica have caught a rare, virtually intact specimen of Mesonychoteuthis hamiltoni (or "colossal squid") -- a very large, very aggressive squid with scores of razor-sharp hooks on its tentacles. Includes article round-up, photos and email from Steve O'Shea.

A cache of ancient Burmese amber has revealed something completely unexpected: an extinct squidlike organism called an ammonite, which swam Earth’s seas while dinosaurs dominated the land. This is the first ammonite and one of the very first marine organisms ever found in amber; because the gemstone is fossilized tree resin, it traps mostly land organisms.

A paradigm-shifting discovery in how specialized organs in squid skin, called chromatophores, contribute to their color and pattern switching feat via an elegant interplay of pigmentary action and structural coloration.
2019-03-12 This Octopus's Dreams (Maybe) Were Written All Over Its Body (Live Science)
Octopuses are known for their astonishing ability to rapidly shift their skin color and texture, to hide from predators, to sneak up on prey and to communicate with each other. But what exactly is going on when octopuses change color in their sleep? (Video)
2019-02-23 Paper Nautilus, Octopus Of The Open Sea (JSTOR)
Paper nautilus is actually the name for the shell of female Argonautidae. This family of small octopuses lives in the pelagic (open ocean) zone rather than near the seafloor like most octopuses. They are unrelated to the better-known chambered nautilus.
2019-02-21 Squid Teeth Could Help Make Bioplastics & Self-Repairing Clothes (New Scientist)
Squid have tough, serrated suckers at the end of their tentacles known as squid ring teeth (SRT). A protein in SRTs can be turned into fibres and films for making tough, flexible and biodegradable plastics. Melik Demirel at Penn. State University and his team have genetically engineered E. coli bacteria to grow it.
2019-02-19 New Squid Genome Shines Light On Symbiotic Evolution (Quanta)
Researchers hope that the genes of Hawaiian bobtail squid (Euprymna scolopes), which use symbiotic microbes (Vibrio fischeri) to produce camouflaging light, can illuminate how animals evolved organs for beneficial bacteria.

Curator Devin Dumont of the Marine Education Center and Aquarium at Skidaway, GA: "I noticed this cloud of moving dots and I realized, 'Oh my God, she had babies. There are babies. There are babies everywhere.' And a sort of panic ensued. I immediately started scooping them out and putting them in buckets and there were just buckets and buckets and buckets full of tiny octopi."

2018-10-26 That Adorable Baby Octopus Is Actually a Pea-Sized Killer (Earther)
An image of a pea-sized cephalopod (O. cyanea or O. ornatus) has been making the rounds this week as the result of how cute this tiny squish appears at first glance. But make no mistake, even a baby octopus can be a cold-hearted killer—and there's photographic evidence to prove it.
2018-10-17 Elucidating Cuttlefish Camouflage (Max-Planck-Gesellschaft)
Computational image analysis of behaving cuttlefish reveals principles of control and development of a biological invisibility cloak. Cephalopods control camouflage by the direct action of their brain onto specialized skin cells called chromatophores, that act as biological color "pixels" on a soft skin display. Cuttlefish do not match their local environment pixel by pixel. Instead, they seem to extract, through vision, a statistical approximation of their environment, and use these heuristics to select an adaptive camouflage out of a presumed large but finite repertoire of likely patterns.
